Start With $10,000 and Retire a Millionaire

This caught my eye because with the current ecomnomic situation I don't see how this is possibl any more . The articale gives the ages and the staticis for your age . They say how you will be caught up in some troubles possibly but not to give in because it will hold you back . It also says that to save you must understand how to spen ? Do we truly know how to save ? http://finance.yahoo.com/retirement/article/112585/start-with-10k-retire-millionaire-marketwatch?mod=oneclick
